best of luck

If we say 130hp NA (turbo just removed)

14,5PSI ~ 260hp
29PSI ~ 390hp

( But I guess 2 bars / 29PSI should be sufficient. )

"some boost required"

are you stateside or the right side of the pond?

Right side of the pond yes

30psi is not all that much. I'll order 2 sets of cylinders, so I can test if they can handle up to 45PSI

So more than 30
Hesd studs may give ya some trouble at those pressures:Last time I had my bug at the track,I had a waste gate failure resulting in a 40 plus psi situation.it BROKE 4 lower 8mm chrome moly head studs,lifted the 3/4 head & made a REAL mess of the track.
